iphone - How to use sqlite in ios 7?

Question

How to use sqlite in ios 7? I'm trying to use code ios 6 and it does not work in ios 7

UPDATE!

I export a database, to desktop, change name and drag and drop to xcode Add the code:

// SQLite
// Conexion DB
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [paths objectAtIndex:0];

_databasePath = [documentDirectory stringByAppendingPathComponent:@"ambisi_test.sqlite"];
[self loadDB];
// --> End SQLite



-(void)loadDB{
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [paths objectAtIndex:0];

NSString *writableDBPath = [documentDirectory stringByAppendingPathComponent:@"ambisi_test.sqlite"];

BOOL exito = [fileManager fileExistsAtPath:writableDBPath];
if(exito) return;

NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"ambisi_test.sqlite"];

BOOL exit = [fileManager copyItemAtPath:defaultDBPath toPath:writableDBPath error:&error];

if(!exit) NSLog(@"%@",[error localizedDescription]);

}

- (void) clickFavorites{

sqlite3 *database = NULL;
sqlite3_stmt *sentencia = NULL;

// Si la BD se ha abierto bien
if(sqlite3_open([appDelegate.databasePath UTF8String], &database) == SQLITE_OK){
    // Genero la query
    NSString *sql = [NSString stringWithFormat:@"INSERT INTO estaciones ("id_number", "name","addres","latitude","longitude") VALUES ("%i","%@","%@","%f","%f")", self.modelAnnotation.number, self.modelAnnotation.name,self.modelAnnotation.address, self.modelAnnotation.lat,self.modelAnnotation.lng];
    NSLog(@"%@",sql);
    // Si esta no contien errores
    if(sqlite3_prepare_v2(database, [sql UTF8String], -1, &sentencia, NULL)==SQLITE_OK){

        // Si la estación no existe ya como favorita, la almacenaré, o en el caso contrario la elimnaré
        if(![self isFavoriteWithIdStation:self.modelAnnotation.number database:database]){
            // Insisto hasta que se inserte
            if (sqlite3_step(sentencia) != SQLITE_DONE){
                 NSLog(@"Error in INSERT step: %s", sqlite3_errmsg(database));
            }else{
                // Ademas de cambiarle la imagen
                UIImage *image = [UIImage imageNamed:@"quitar-favorito"];
                [_button setBackgroundImage:image forState:UIControlStateNormal];
            }

        }else{ // La elimino de favoritas
            // Genero la query
            NSString *sql = [NSString stringWithFormat:@"DELETE FROM estaciones WHERE id_number = "%i"",self.modelAnnotation.number];
            // Si esta no contien errores
            if(sqlite3_prepare_v2(database, [sql UTF8String], -1, &sentencia, NULL)==SQLITE_OK){
                // Insisto hasta que se inserte
                if (sqlite3_step(sentencia) != SQLITE_DONE){
                    NSLog(@"Error in DELETE step: %s", sqlite3_errmsg(database));
                }else{
                    // Ademas de cambiarle la imagen
                    UIImage *image = [UIImage imageNamed:@"addfav"];
                    [_button setBackgroundImage:image forState:UIControlStateNormal];
                }
            }
        }
    }else{
        NSLog(@"Error making INSERT: %s",sqlite3_errmsg(database));
    }
    sqlite3_finalize(sentencia);
}else{
    NSLog(@"Doesn't open Database: %s",sqlite3_errmsg(database));
}
sqlite3_close(database);

}

- (BOOL) isFavoriteWithIdStation:(int) idStation database:(sqlite3 *)db{

sqlite3_stmt *sentencia = NULL;
NSString *sql = [NSString stringWithFormat:@"SELECT id_number FROM estaciones"];
NSLog(@"%i",idStation);
NSString * ide = [NSString stringWithFormat:@"%i",idStation];
if(sqlite3_prepare_v2(db, [sql UTF8String], -1, &sentencia, NULL)==SQLITE_OK){
    while(sqlite3_step(sentencia) == SQLITE_ROW){
        NSLog(@"%i",idStation);
        NSString *number = [NSString stringWithUTF8String:(char *) sqlite3_column_text(sentencia, 0)];
        //NSString *id_tutorialString = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)];
        if([number isEqualToString:ide]){
            NSLog(@"NUMBER:%@",number);
            NSLog(@"NUMBER:%i",idStation);
            sqlite3_finalize(sentencia);
            return YES;
        }else{
            NSLog(@"Error en el condicional");
        }

    }
}else{
    NSLog(@"Error making SELCET: %s",sqlite3_errmsg(db));
}
sqlite3_finalize(sentencia);

return NO;

}

The error is triggered in the NSLog (@ "Error making INSERT:% s", sqlite3_errmsg (database)); and the response has been making INSERT Error: file is encrypted or is not a database

I've also tried to recreate the DB and import it several times, but still with the same error..

In the iOS simulator iOS 6 if it works but in iOS7 is not working ... is rare, someone tried to use SQLite in iOS7? ..

I hope you can help me, thanks!

Answer 1

You should look at error codes.

Thus, the line that says:

NSLog(@"Error making INSERT");

should say:

NSLog(@"Error making INSERT: %s", sqlite3_errmsg(database));

Likewise the line that says:

NSLog(@"Error la SELECT");

should say:

NSLog(@"Error la SELECT: %s", sqlite3_errmsg(database));

Only by looking at those error messages can you effectively diagnose the problem.

---

You report that it says: "file is encrypted or is not a database"

That suggests that your database has gotten corrupted somehow (assuming you never used encryption). You'll want to recreate it.

---

Unrelated to your broader problem, your code for the INSERT statement bears a line that says:

// Insisto hasta que se inserte
while(sqlite3_step(sentencia) == SQLITE_OK);

That should be:

if (sqlite3_step(sentencia) != SQLITE_DONE)
    NSLog(@"Error in INSERT step: %s", sqlite3_errmsg(database));
